I should be painting my car spring break, in two weeks. I should be installing it then. When I pulled the long trim on the rear window up it seemed to push back in just fine. If it cant be put in though I will have the window pulled and then reinstalled with the new trim. I bought the corner and the long side/corner trim new. I will let you know how it goes. And I can do a write up besides I already pulled the long trim, and I will not be doing the top piece.
